Abstract  Abstract

PROBLEM TO BE SOLVED: To provide a method for adjusting a receiver timing of a wireless device in a Coordinated Multipoint (CoMP) system.

SOLUTION: The wireless device receives a plurality of node specific reference signals (RSs) from a plurality of cooperating nodes in a coordination set of the CoMP system. The coordination set includes at least two cooperating nodes. The wireless device estimates a composite received RS timing from a plurality of received RS timings generated from the plurality of node specific RSs. The received RS timings represent timings from the at least two cooperating nodes. The wireless device adjusts the receiver timing on the basis of the composite received RS timing. A node specific RS includes a channel-state information reference signal (CSI-RS).
